What does "clearance" refer to when calling for fire?

The concept of "clearance" when calling for fire is primarily focused on ensuring that the area to be engaged is free of friendly forces. This is a critical step that prevents friendly fire incidents and enhances overall operational safety. Before engaging a target, it is essential for the unit calling for fire to confirm that their personnel and any allies are not in the line of fire, as artillery or air support can have significant collateral consequences if friendlies are inadvertently targeted.

This step is paramount for maintaining unit cohesion and effectiveness, as well as safeguarding the lives of those who are on the battlefield. By thoroughly checking for the presence of friendlies in the potential impact area of the fire support, leaders can act decisively while adhering to the principles of responsible fire support coordination.
